WORKING WITH HOST AUDIO SOFTWARE
61
Streaming computer audio to and from the
on-board mixer
In the Routing grid, you’ll see mixer inputs across
the top of the grid, including Main, Monitor, Aux,
etc. (item 11 on page 15). These are output busses
from the LP32’s on-board mixer. To route one of
these mix busses to your host computer software,
click the grid at the intersection of the mix column
and desired computer channel row. Now, the mix
bus output will be routed to the computer via the
channel you selected.
Conversely, you can stream audio from the
computer into the mixer. Channels coming from
the computer are represented across the top of the
routing grid as inputs. To route a computer channel
to the mixer, click the grid at the intersection of the
computer channel column and the desired mix
input row. Now, that computer channel will be
routed to the mixer input.
Working with AVB network streams
Audio channels going to networked AVB interfaces
can be streamed to and from your host audio
software through the LP32 connected directly to
the computer. For information about how to set
this up, see “Mapping computer channels to
network streams” on page 91.
Mirroring computer channels to multiple
outputs
Figure 7-6 shows an example of mirroring one
stereo audio stream from host audio software to
several outputs. In the example, computer
channels 1-2 are being sent to Phones L-R and
ADAT bank A 1-2. To route a source to multiple
destinations, click multiple boxes in its column,
(see computer channels 1-2 in Figure 7-6).
Combining multiple sources to one output
To merge (mix) any channels in the grid (computer
streams or otherwise), route them to mixer inputs
and then use the on-board mixer (“Mixing tab” on
page 16).

WORKING WITH ON-BOARD MIXING AND
EFFECTS
The LP32 provides powerful mixing, EQ,
compression and reverb, which can operate hand-
in-hand with your host’s mixing environment. For
example, the LP32 can serve as a monitor mixer,
routing channels to musicians, or it can serve as an
integrated extension of your host’s mixing
environment. You can even save a particular
mixing configuration as a preset for future recall.
For details, see “Mixing tab” on page 16.
